PUMPING AND PULLING APPARATUS FOR WELLS AND THE LIKE.

Application filed July 15, 1921.

which is mounted a system of shafting,

gears, chains, etc., whereby an exterior source of power may be introduced to the pump rods in the Well or may be used for hoisting or pulling the rods, tubes, etc.

An object of the invention is the provision of a simple unitary apparatus for pumping wells and pulling rods and tubing from wells and the provision of an apparatus which can be easily installed for use in oil fields and particularly for use with deep wells ranging from 2000 to 3500 feet, the construction particularly adapting the apparatus for use with wells necessitating pumping with a long stroke and wells necessitating pump operation at high speed.

In the accompanying drawings I have shown one form of specific embodiment of my invention. In these drawings,

Fig. 1 is a side elevation of the well, pumping and pulling apparatus;

Fig. 2 is a top plan view of Fig. 1;

Fig. 3 is a section along line 33 of Fig. 2;

Fig. 4 is a section along line 44 of Fig. 2;

Fig. 5 is a detailed section of the quill and pulley;

Fig. 6 is a detailed section of the head and Fig. 7 is a detailed segmental section of the crank.

Referring to the drawings, 1 indicates the steel or other supporting frame having the uprights 2 securely attached thereto by the angle iron plates 3. Attached to the frame are I-beam supports 4 upon which are mounted the journal bearings 5 and 6. The bearing 5 accommodates a hollow shaft or quill 7 which is keyed, by means of the key 8 to the drivin pulley 9 driven from a source of power not shown). This hollow shaft or uill 7 carries a sprocket wheel 10 keyed on t e quill by key 11 and it also has keyed thereto. by means of the key 12 Serial No. 485,143.

one-half 13' of a flange coupling. The other half 14 of this flange coupling is secured to the half 13 by means of bolts and nuts 15 and it in turn is keyed to shaft 16 by means of the key 17. On the other end of the shaft 16 is a fly wheel 18. The flange coupling 13 and 14 may be replaced by means of a clutch if desired. This construction permits disconnecting the shaft 16 from the quill 7 in order that mechanism, hereinafter described, operated by the shaft 16 may be thrown out of engagement. The left hand end of the shaft 16 carriesa pinion 19 meshing with the gear 20, both the pinion and the gear being located in an oil tight, oil filled casing 21. The driven gear 20 is mounted upon the shaft 22 which drives the crank 23 such crank in turn operating the connecting rod or pitman 24. The stroke of this connecting rod or pitman may be altered by placing it on the crank 23 at any one of a plurality of holes 25 (3 being shown). This pitman 24 is advantageously hollow and contains lubricating oil. In Fig. 7 I have shown a detailed section of one of the ends, both ends being the same. The rod 24 is provided with the bearing 26 for encircling the pin 27 of the crank arm, and such bearing 26 is provided with a hole 28 having a wick 29 leading to the hollow pitman 24. The end of the pitman is provided with a piece of wire gauge or other material 30 holding the wick in place. In this manner the pins 27 and 31 are thoroughly lubricated. The pin 31 is carried by the block 32 which by means of bolts 33 is secured to the depending arm 34 of the quadrant designated as a whole by 35. The arms 36 and 37 support the quadrant by means of rivets 38- or other suitable fastening devices. The quadrant 35 is provided with a pair of channel guides 39 for the reception of the cables 40. This quadrant is positioned directly over the center of the well and it carries at its upper end the bracket 41 to which are secured the adjusting bolts 42 with the nuts 43 carrying the cables 40. These cables may be adjusted on the bolts 42 by means of the nuts, as shown. The pump rod (not shown) is clamped in the center between the cables so that the length of the pump rod does not interfere with the operation of the quadrant, the rod may pass up vertically against the face of the quadrant and between the cables. Whenthe quadrant descends if the rod clamp 46 with its cables does not immediately descend owing to the rod sticking in the stufling box or otherwise the cam 45 will'hit the upper end of the clamp and cause it to move.

The arm 36 extends some distance to the rear and carries concrete blocks 47 as a counterbalance. The whole quadrant is suitably iournaled in the supports 2 by means of the s aft 48 operating in the trunnions i9, the head 50 being carrled by the shaft 48. A lubricating device such as a grease or oil cup 51 is used.

The operation of the apparatus as thus far described is obvious. The vertical straight line reciprocating motion is imparted to the cables by means of the crank and pitmanconstruction-described, operating to move the quadrant inan arc of a circle through its connection to the su ports 2. The cables 40 being flexible will al ow the pump rod attached to the clamp tti to descend and rise in a vertical line.

It is necessary at times to Withdraw the tubing and rods entirely from the well. For this purpose I have provided a cable drum which may be operated from the same source of power as the quadrant operating device. Attached to the main frame l are two A frames 55 carrying at an elevation the journal boxes 56. The drum 57 is mounted on the shaft 58 and such shaft is carried in the journal boxes 56. The sprocket wheel 59 is keyed to the shaft 58 and is driven by means of the chain 60 operated from the sprocket 10 driven by the quill keyed to the ti wheel 9. The drum 5? is provided with t e head or end 61 and with a spacing device 62 which may be adjusted anywhere along the line on the drum 57 by means of the bolt 63. This drum is of a length and diameter which permits it to handle cable from any ordinary well. The spacer 62 is split as is indicated and may be taken oh if necessary or can be moved back and forth so that a pulling line and a sand linecan be used at the same time; or so that the drum can be lagged up in case faster speeds are desired at any time. @111 one end of this drum is a brake band 64L over which is mounted the brake 65 operated by the lever 66 extending in a most convenient location with respect to the well. When it is necessa to pull the rods or the tubes from the wel the chain is placed on the gear and sprocket deneeaeee scribed. When it is desired to stop pumping and pull the rod or tubing, it is only necessary to take out the two bolts in the coupling between the quill and the drive shaft and put on the chain. This disconnects the pumping rig and connects the pulling rig. The pin in the crank shaft may then be moved and the quadrant swung down outof the way giving ample room between the jack frame and the well. The cable used to pull the tubing and rods from the well passes from the drum over a pulley on a derrick over the well (not shown).

The whole structure is suitably. braced as for instance by the arms 67 and the frame carrying the quadrant 35 braced by the arm 68.

What llclaim is l. A machine of the character described, comprising a frame, a quadrant pivotally supported thereby, a clamp flexibly connected to the quadrant, means carried by the quadrant in its downward movement for forcing the clamp downward in its downward movement, and a pitman for rocking said quadrant.

2. A machine of the character described, comprising a frame, a quadrant pivotally supported thereby, a clamp flexibly connected to the quadrant, means carried by the quadrant for engaging the clamp on its downward movement for forcing the same downward, a pitman connected to the quadrant, a driven shaft, a crank carried by the shaft, and means for adjustably connecting the pitman to the crank.

3. A machine of the character described, comprising a frame, a quadrant pivotally connected to the frame, a clamp flexibly connected to the quadrant, means carried by the quadrant for engagin the clamp on its downward movement for forcing the same downward, apitman connected to the quadrant, a driven shaft, a crank connected to the shaft, and having a series of openings therein and a wrist pin connected to the pitman and adapted to be secured in any one of the series of openings in the crank.
